Gents! & Ladies?! Can someone comment on this? I figgured that multicast with PIM should work while working with iptables: We need to allow for IGMP to reach the PIM deamon, the PIM deamon needs to communicate and we need some ip traffic to allow from normal IP to multicast adresses and or ranges. Anyone who got experience with it? Can't find any usefull info in FAQ and Google, but maybe I'm googleing the wrong way? Maybe someone from the developers who can tell how iptables handles IGMP & multicast IP. Kind regards, Arnoud Buurman
